You did see that there were over 300 vulnerabilities in iOS reported and fewer than 20 on Android?
Like sparksd, I have been an Android user for several years and haven’t had a problem. “Some people” could be anyone. “Some people” could make disparaging comments about iOS.
I wouldn’t use an iPhone if you gave it to me. Obviously, lots of people don’t share my sentiments.
The most recent Android security scandal (like 1-2 months ago) found OEM's have falsely been claiming to be applying security patches. So the OS was reporting you were up-to patch level March 2018, but the vendor did not apply the actual patches to give you the expected protection.
I don't claim iOS is perfect. It certainly is being patched by Apple on a regular basis, but at least we know everyone can get and install those updates on day one. And Apple users can trust Apple is actually patching the issues they report to be fixing.
